摘　　要：由于社会经济发展及人们生活的需要,北京山区工程建设不断增加,随之而来的还有扬尘、有害气体及重金属微粒等大气污染。近年来利用植物进行大气环境修复受到人们的重视,植物修复具有绿色、低耗、安全及可持续等优点,是最经济有效的大气污染修复措施。榆树作为华北地区乡土树种,对北京山区的气候条件及土壤条件适应性强,用作绿化树种成活率高;此外,榆树叶片滞尘能力强,对二氧化硫气体及重金属微粒具有抗性和吸收能力,对二氧化碳吸收固定能力强,也能吸收氮氧化合物,是较为理想的大气环境污染修复树种;本文通过对比北京山区建筑工程大气污染主要成分与榆树生理特征,总结榆树对北京山区建筑工程施工大气污染修复的作用,从而得出榆树对北京山区建筑工程施工现场大气污染修复的可行性。Due to the social and economic development and the needs of people's life,the construction of the mountainous area in Beijing has been increasing constantly,followed by air pollution such as dust,harmful gases and heavy metal particles.In recent years,the use of plants for atmospheric environmental remediation has attracted much attention.Phytoremediation has the advantages of green,low energy consumption,safety and sustainability,and is the most economical and effective air pollution remediation measure.As a native tree species in North China,elm is highly adaptable to the climate and soil conditions in Beijing mountainous area,and has a high survival rate as a greening tree species.In addition,elm leaf dust retention ability is strong,to sulfur dioxide gas and heavy metal particles have resistance and absorption capacity,to carbon dioxide absorption and fixation capacity is strong,can also absorb nitrogen oxygen compounds,is a more ideal atmospheric environmental pollution remediation tree species;By comparing the main components of air pollution and the physiological characteristics of elm in construction projects in Beijing mountainous areas,this paper summarized the effect of elm on air pollution remediation in construction projects in Beijing mountainous areas,and then concluded the feasibility of elm on air pollution remediation in construction sites in Beijing mountainous areas.
